The complaints do seem pretty absurd. Looking purely at the design and articulation of the figure, it's clear that the people at Hasbro learned a lot from the SA trooper heyday of 2005 - 2012, and utilized some of the best techniques into the design and engineering for the First Order Stormtrooper. This trooper is awesome in terms of the sculpt and articulation.
As for the helmet paint apps? That's something that can be dealt with merely by having a discerning eye when you're shopping in the store. I've seen some troopers with better paintjobs than others. If anything, this is a QC issue and not a design error. And it seems like something that could be resolved in a later wave.
